TIE-PLATE FOR RAILS.

Specification of Letters Patent.

Patented July 18, 1922.

Application filed July 12, 1921, Serial No. 484,144. Renewed April 15,1922. Serial No. 553,014.

To all whom it may concern:

Be it known that I, EPNEST N. JoHNsoN, a subject of the King of GreatBritain, and a resident of the city of Winnipeg, in the Province ofManitoba, Canada, have invented certain new and useful Improvements inTie-Plates for Rails, of which the following is the specification.

The invention relates to improvements in tie plates for railsparticularly as used on railroads and an object of the invention is toprovide a tie plate which will effectively support and fasten the railbase to the tie and which will prevent creeping of the rail in eitherdirection.

A further object of the invention is to construct the tie plate so thatit will accommodate the varying widths of rail bases and so that it canbe adjusted to firmly and positively grip the inserted base of the rail.

A further object is to construct the tie plate in a simple and durablemanner and so that no special tools are required for ad justing purposesor for fastening to the tie.

WVith the above more important objects in view the invention consistsessentially in the arrangement and construction of parts hereinaftermore particularly described and later pointed out in the appendedclaims, refer ence being had to the accompanying drawing in which Fig. 1is a plan view of the tie plate as it appears in use.

Fig. 2 is a vertical cross sectional view through the tie plate andrail.

Fig. 3 is a vertical longitudinal sectional View at 3-3 Fig. 1, the railbeing removed.

In the drawing like characters of reference indicate corresponding partsin the several figures.

The rail 1 presents the customary head 2, web 8 and base 4 and it iscarried by my tie plate 5, the tie plate being mounted on and secured tothe customary tie 6. The tie plate comprises a substantially rectangularbase or bed plate 7 which sits on the tie beneath the rail and has theunderside provided with projecting V-shaped grips 8 which bite into thetop face of the tie. The ends of the bed plate which it will be observedextend considerably beyond the base of the rail are provided with spikeopenings 9 which receive the customary pairs of spikes 10 and 11 whichare driven in through the openings to permanently fasten the bed plateto the tie.

The outer end of the tie plate is provided with a stationary jaw 12which is adapted to receive the adjoining edge of the rail base for thefull length of the jaw. The jaw is suitably reinforced by webs 13 castintegral with the base plate and the i aw. The other or inner end of thebase plate is formed with an integrally cast upstanding guide orabutment 14: positioned somewhat back from the inner edge of the railbase, the abutment being suitably reinforced by webs 15 similar to those13.

Here it isto be observed that this guide or abutment presents twotapering faces 16 and 17 at the side towards the rail, the said taperingfaces meeting centrally of the base plate at which point they areclosest to the rail base. Further, it will be observed that the innerside of the abutment is undercut so that the faces 16 and 17 areinclined and form an acute angle with the base plate. In actual practicethe taper is approximately one inch in twelve inches.

Between the abutment or guide and the base of the rail I locate similarright and left wedge blocks 18 and 19 which have their inner sides orthose remote from the rail formed complementary to the inner face andtop of the abutment and their outer sides or those next the rail formedcomplementary to the edge of the rail base and slightly overhanging thesame. The upper parts of the wedge blocks are oppositely screw threadedto receive the right and left hand screw threaded ends of an adjustingscrew 20 extending parallel with the rail and having the central portionthereof formed at 21 to receive a wrench or similar tool.

According to the above arrangement it will be apparent that by turningthe screw in one direction or the other one can draw the wedge blockstowards each other or spread them apart and by so doing jam or releasethe rail base between the wedge blocks and the aw 12.

The base plate is cut away beneath the wedge blocks to provide aclearance space 22 and it is fitted at the sides with extending guidelips 23 and 24:.

When the tie plate is to be used it is spiked to the tie and the wedgeblocks are spread apart to permit of the insertion of the rail base.After the rail base has been put in place with the outer side entered inthe aw 12 the sectionman tightens up the wedge blocks by operating thescrew in a proper direction to draw them together. lVhen the wedgeblocks have been tightly drawn in to jam the rail the work is complete.

This tie plat-e not only makes a permanent and solid base for the railbut it also prevents creeping of the rail in either direction. Obviouslyif the rail attempts to creep in one direction one of the wedge blockswill tighten up and the other release whilst the reverse occurs if therail attempts to creep in the opposite direction.

What I claim as my invention is 1. A rail fastening, comprising a baseplate means thereon engagable with one edge of a rail base an abutmenton the base plate spaced from the opposite edge of the rail base, aretaining member removable on the base plate for wedging engagementbetween said abutment and the adjacent edge of the rail base and meansconnected to said retaining member for moving same in oppositedirections.

2. A rail fastening, comprising a base plate, presenting spacedabutments, one of which is engageable with one edge of a rail base, apair of wedge blocks mounted for wedging engagement between the oppositeedge of the rail base and the remaining abutment and means connected tosaid blocks operable to move the same toward one another into railgripping relation or away from one another to release the rail.

3. The combination with a rail and a tie, of a base plate mounted on andspiked to the tie and carrying the base of the rail and provided at oneend with an upstanding stationary jaw receiving one edge of the railbase and at the other end with an upstanding abutment spacedfrom theother edge of the rail base the said abutment presenting undercutoppositely tapered faces at the side adjacent the rail and with thefaces tapering away from the rail at their outer ends, a pair of wedgeblocks inserted between the -tapering faces and the latter edge of therail base said blocks having the upper parts thereof provided withaligned openings oppositely screw threaded and an adjusting screw havingthe ends oppositely screw threaded and received within the screwthreaded openings of the blocks.

Signed at lVinnipeg, this 17 day of June.
